Finally could I be pregnant??

Sheila
So my boyfriend and I had unprotected sex on may 29th five days before my period. He did cum inside me which I didn't know until he pulled out (missionary we were engaged in) and I felt his semen dripple out and he looked down to watch it come out then we continued missionary after that. Now I have a little pain in my left uterus only when moving fast or standing up. Also sometimes I feel sharp pain on my left rib area every now and then. And loud gassy feeling in my stomach. Could I be pregnant?
